We've installed an evaluation version of JIRA Core and hit the following problem:
When trying to open certain pages (reports, mainly) in IE we sometimes get "invalid characters found in the request target" error from Tomcat. This only happens in IE (Chrome and Firefox do fine) and only when working with a project or task that has non-ASCII (Russian cyrillic) characters in its name - hence, those are present in the link that's used to open the report. Here's an example:
http://jira-test:8080/secure/ConfigureReport!default.jspa?selectedProjectId=10106&projectOrFilterId=project-10106&projectOrFilterName=Тест&reportKey=com.atlassian.jira.jira-core-reports-plugin:pie-report
I've done some digging, and it seems that we've hit this issue: https://blogs.msdn.microsoft.com/ieinternals/2014/04/22/unicode-in-url-changes-for-ie11/
As far as I can tell, there's no resolution to this short of not relying on IE for proper encoding and doing it via some other means, feeding IE links that already have non-ASCII characters processed. I checked this by opening a page that gives error in IE in Firefox and copy-pasting address field contents from Firefox to IE - it works fine when I do that.
Is there a solution for this available? IE is still standart in our company (for reasons... well... arcane, basically), and we cannot use JIRA with it atm.
Thanks in advance.
